PATENT OFFICE ."BURT A. PETERSON, OF ROCKFORD, ILLINOIS, ASSIGNOR TO BARBER-COLMAN COMPANY,

F ROCKFORD, ILLINOIS,"A CORPORATION 0F ILLINOIS WARRING APPARATUS j A Application le'dune 6,

The object of the present invention is yto eXpedite Creel replenishment and thusl reduce idle time of the warper. This object has-been attained by providing a creel of such construc- *n tion that it may be loaded with a new setof cheeses while-thewarper is running, the arrangement being such that the new set of cheeses may be quickly and conveniently` unwound. v v l VIn the accompanying drawings,

Figure lis a side elevation ofawarping apparatus embodyingfthe features of my inlevention. Fig. 2 is a plan view thereof. Y

Fig. 3 is a vertical sectional view in the plane of line 3-3 of Fig. 2.

Fig. 4 is a view looking from the right- Ahand side of Figr. 1 1 W Fig. 5 isa fragmental perspective view of the Creel. y A Y I Fig.r6 isa detail view'of the 'thread guiding means. i

- As shown in Fig. 1,the apparatus comp 8prises a warper A and acreel B." In the' present instance, I have shown a beam warp- Q er, but it will be understood that the invention is applicable as well to-l aball warper. For

Va disclosure of. a warper in connection with 'which the present invention may be used,

reference maybe made to my application Serial No. 706,834, filed April 16, 1924, which application `will .mature into Patent No. 1,672,470 on J une 5, 1928.

v While the Creel B may partake of-various forms, it is herein shown as comprising -two upright frames 1 and 2 `which are adjacenteach other at one end and separatedy fromeach other at the opposite end so as to consti-v 5o in this instance, two parallel bottom frame on the other series of supportsfare'being tute a V-shaped structure. The framesl and 2 are rigidly connected together at theirl ad' i928. serial No. 283,244;y

members 5 and`6, transverse connecting members 7, a longitudinal top member 8, end members 8, anda series of Woodenposts 9 Connecting the 'lower and upper frame members 5 and 8.VK Each of the frame members 1 and 2 further comprises a series of Creel sections 10 (Fig. 3). Each creel section consists of an upright 11 rotatablysuspended from a trolley or carrier 12 adapted to run within a tubular track 13 which issecured tothe lower sides-of the cross-barsl 4 parallel with the frame members 5, 6 andl 8. Projecting from the lower end of the upright 11 is a guide Vstud14 that extends slidably within the space between the upper flange of the yframe member 6 and a rail 15 secured to the transverse members 7.? To space apart the uprights 11, each of the creel sections 10 comprises y horizontal distance piecesv 16 proj ecting from opposite sides of the uprights 11- inposition to abut the distance pieces on ad-4 jacent creelsections. y Y

While certain features ofthe invention are` adapted for use inconnection with the unwinding of yarn masses of various forms and types, Ifhave herein shown the creel sections 10 as especially adapted 'to support c rosswound cylindrical yarn masses of the' type l commonly termed cheeses,v 1n thev draw'- ings the cheeses are indicated at a. Each conf sists of yarn spirallywound upona tubular core 6 (Fig.f3) The cheese is non-rotatably inountedupon a spindle 17 rigidlyfsecured to the-upright 11. v,A curved leaf spring 18 secured in a groove in the periphery of the spindle 17 projects out of saidy groove suffi-A ciently to engage the'interior of the cheese core and eXert's suicient pressure against the core to hold thecheese against rotation'and to insure that the, cheese shall not be casually displaced from the spindle. Surrounding each spindle is a cylindrical casing 19 having a closedend- 20 which is rigidly secured to the upright 11. The opposite end of the casing isopen for the insertion of'full cheeses and the removal of Cheese cores.

As shown in Fig. 5, the spindle l17 and casings 19 are/arrangedin'ftwo columns, one on'eachside of theupright 11, the' casingsj on'a given side of the upright being in con-y V10o `creel sections.

The spindles 17 may be considered as arranged in pairs, onespindle'of eachpair being accessible from the interior of the creel frame while the other spindle is in unwinding position. ,The spindles of each pair are axially alined. L 'Y ,Y

When unwinding yarn from a stationarilymounted cross-wound yarn mass, lint vcollects on the rear end of the yarn mass, unless pre.- vented from so doing. Such accumulation of lintis objectionable, as it is carried ofiV by the yarn in bunches. Ina certain prior-art warper, electric fans located outside the creel are. employed to prevent lintfrom settling ontheyarn-masses. One of the functions of the casings 19 herein disclosed is to enable the balloovILng yarn toset up air currents that blow the lint out toward the front of the creel and thus prevent lint from accumulatingY on the yarn masses. Another functionV of the casing 19 is to keep the ballooning threads out vof contact with one. another.

When the creel sections 10 are compactly arranged in runningposition (as sho-Wn in F ig. 1 and inthe right-hand portion of Fig. 5), one column of cheese supports on each creel section faces toward the outer side of the creel, whilethe other column of cheese supportsfaces toward the inner side of the creel,

thus permitting loading of the last mentioned column of' cheese supports while a set of cheeses is being unwound. Y

After fillingpthe reserve or inner sides of theA creel sections, the operative collects the i threads of each column, beginning at the top of. the column anddrawing the thread ends dawn to.Y the bottom. To hold the threadA ends in place until the time arrives to draw them forwardto the-warper, thereis Vprovided aL clipl or holder 21 on the lowermost casing 19 (see Figs. 3,4 andt).

vrhe devices for guiding the yarn inits course from the cheeses to the warper and the meansk forV detecting exhaustion of the yarn are supported upon the posts 9. On the inner side of each post is a series of yarn guides, herein shown as formed by means of a plate 28 (Figs. 3 and 6)` having openings 24Veach formed in axial alinement with one of the cheeses being'unwound. A slot 25 extends from the edge of the plate to the opening 24CA to admit the yarn to the latter. On the inner side of the plate 23 is secured a yarn guide 26 which is alined with the axis` of the cheese. The yarn guide 26 is in the vform of a curvediinger, its closed-side being opposite the entrance slot25.

The'operation of. replenishing the creel is' as follows :The cheese-spindles at the'inner i side of then-creel are suppliedY with. cheeses tions to be slid successively away from the next adjoining creel section to permit of turningthe creel section to place the newly loaded-'side thereof at the outer side of the creel. YAll of thecreel sections having been 'thus turned, they are pushed up toward the front end of the creel (as shown in Fig. l), in readiness to be `connected to the beam.

`Vhile the present embodiment of the invention has been described in considerable detail, it will be understood that various modiications ofYV details and rearrangements of mechanisms may bemade., within the scope of the appended claims, without departing from the spirit of the invention.

I claim as my invention:

1. A V-shaped warper creel comprising twoframes. arranged in vertical planes that converge inftheform of a V, creel sections in each of said frames, said sections being slidable longitudinally of the respective frames toward and'V away from the apex of the V- shaped creel, each of said creel sections comprising pairs of yarn mass-supports, one support of each pair being accessible from one side of the frame for replenishment while the other support of the pair is in unwinding position, and said pairs of support being rotatable. on an axis located between the supports, and yarn guiding means on the outer side-orf each of said frames for guiding the yarn inthe general direction of said apex.

2'. A warper creel comprisingl a frame, creel sections independently movable longitudinally of said frame and'always occupying the same plane, each of said sections comprising pairs of yarn mass supports, one support of each pair being accessibleA from one side of the frame for replenishment whilethe other support of the pair v'is in unwinding position, and said pairs of supports being rotatable on an l,axis located between the supports.

3. A creelV comprising a vertical series of yarn mass supports, each being arranged to support ayarn mass on a horizontal axis, and a casing enclosing each support and having an open vertical side for the insertion of the yarnl mass and the withdrawal of the yarn, theballooning yarn in said casings setting up air currents that blow the lint out of the casings. f

In testimony whereof, I have hereunto affixed my signature. Y
